CHAIN-PUMP.

SPECIFICATION forming part of Letters Patent No. 294,434, dated March 4, 1884.

l Application filed August 17, 1F83. ((No model.)

To all whom t may concern,.-

Be it known that I, AUGUs'r BECKMANN, a citizen of the United States, residing at St. Louis, andState of Missouri, have invented a new and useful Improvement in Chain-Pumps, of which .the following is a specication.

' My invention relates to improving that class of pumps or waterelevators in which an end- ,lessv chain with buttons passes upward through wood tubingV or well-curbing; and the chief obj` ect of my improvement is to provide a footsupport with roller attachment, by means whereof the wood tubing can be readily and properly supported inthe well in aplumb line, and the chain with buttons in passing upward be directed and made to enter the mouth or lower end "of the wood tubing in a true perpendicular line, and prevented from striking against and damaging the bore of the tubing, and otherwise incurring the disadvantages of imperfect action and imperfect lift of the water. I attain this object by the mechanism illustrated in the accompanying drawings, in

which- Figure l is a side elevation of an'ordinary chain-pump, showing my improvement applied l to the bottom of the Well-tubing. Fig. 2 is an enlarged sectional elevation of the bottom portion of well-tubing and myimproved foot-support for same, showing the manner in which the chain with buttons is made to enter the lower end of the tubing. Fig. 3 is a plan section taken on line 3 3, Fig. 1. Fig. 4 is a perspective view of the foot-support asitv appears without the roller or sheave.

Similar letters refer to similar parts throughout the several views.

The pump-housing A,with its reel, fixtures, Src., to operate the endless chain, are in manner usual.

B represents the common wood tubing or well-curbing, and C the endless chain, with buttons c arranged in manner usual.

My improvement relates to the foot-support D, with roller or sheave for the purpose of supporting the tubing in a plumb line, and guiding the passage of the chain and its' buttons, and said parts are constructed as follows: The foot-support D is a frame consisting of the inoline sides dd', arranged opposite each other,

united at top by the cross-frame d2, and at botthe chain passes.

of the tubing is seated upon the central crossframe, (Z4. (See Figs. 1,2.) Further, it is essential that the tubing or curbing C should be supported and niountedinthe foot-Support Din a plumb line. Thisaccomplish by making that portion of the face ofthe cross-frame d marked (Z5 a true vertical face, and that portion of the top cross-frame marked d also a vertical face, as shown in Figs. 2, 3, 4. Thusv the ri ght-anglebearin g-face ofthe central crossframe corresponds to the corner edge of the bottom portion of the well-tubing, (see Fig. 2,)

and the inner face, d5, forms acorresponding face at that point, to suit the vertical side of the tubing. (Also shownin Figs. 2, 3.) The well-tubing C seated in a true vertical line in the foot-support D, the parts are fastened and kept together in place by the respective side screws, e e', which, as shown in Figs. 3, 4., en-

ter the tubing so as not to interfere with the bore thereof.

F is along foot-board, forming a base, to which the frame D is kept fastened in position at the bottom of the well.

f is a sheave or pulley-wheel, around which The sheave f turns on an axis-bolt, and is'arranged nearly midway be- -tween the central cross-frame and the bottom of the foot-support, as indicated in Figs. l, 2.

vThe inclined position of the foot-support D locates the sheave sufficiently to one side to permit the chain to pass around the sheave and assume 'a vertical line,preparatory to entering or passing up the bore ofthe well-tubing. also, the buttons of the chain are thus brought in a more nearly horizontal plane,preparatoryv to passing up the bore of the tubing, and the chain and its buttons can thus ascend the tub'- ing without jar or striking and damaging the same, especiallyl the bottom portion thereof.

As apparent, the entire foot-support D (illustrated in Fig. 4) can be made a casting, and asl such can be with or without the ring or collar g. (ShowninFig. 1, 2, 4.) Whenthe collaris cast with the foot-support, it is made to project from and be part of the vcentral cross- IOO frame7 asindicated in Figs. 1,2,4. The collar y just fits to the bottom edge of the bore ofthe tubing, so that the orifice of the collar will be in line with the bore and permit the passage of the chain parts. The collar has its inner face iiaring to suit the Hare inside the tubing, and otherwise by its use the collar helps to support the Well-tubing, as indicated.

By the use of my improvement no difficulty is experienced in setting the Well-tubing in plumb line, since the act of seating samein its place in the foot-support brings and maintains the tubing in its said required position.

Vhat I claim is- 1. In combination with well tubing or curbing, the foot-support D, consisting of 'the inclined sides d d, united by top and bottom cross-frames7 d2 d, and central cross-frame, dt, having the vertical face d, also the inner face of the top cross-frame, beinga vertical face, d, by means whereof the said curbing can be kept supported, in the manner and for the purposes set forth.

2. In combination with the foot-support D, consisting of the inclined frames d d', top and bottom cross-frames7 d2 d, and central crossframe, (Z, said top and central cross-frames having the vertical faces at d5 d, the ring or collar 0, projecting from the central crossframe, substantially as and for the purposes set forth.

3. In combination with the foot-support D, consisting ofthe inclined frames d d', top and bottom cross-frames, d2 d, central cross-frame7 d4, and the vertical faces at df d, the sheavc or pulley-wheel f, substantially as and for the purposes set forth.

4. The combination7 with the well-tubing and endless chain in chain-pumps, of the footsupport D, consisting of the incline framesd d', having top, bottom, and central cross-frames, d2 d" (1*, and the vertical faces at ddfgthe sheave f and ring or collar g, to operate in the manner and for the purposes set forth.

In testimony of said invention Ihave hereunto set myhand.

AUGUST BECKMANN.
